# MAA Framework - Roadmap
2+
3+
## Current Status
4+
5+
The MAA Framework repository is configured as a **hub-and-spoke mirror system** that automatically synchronizes code across multiple Git hosting platforms:
6+
7+
- **GitHub** (hub/primary)
8+
- **GitLab** (mirror)
9+
- **Codeberg** (mirror)
10+
- **Bitbucket** (mirror)
11+
12+
---
13+
14+
## Phase 1: Infrastructure & Security (Completed)
15+
16+
- [x] Hub-and-spoke mirror workflow
17+
- [x] SHA-pinned GitHub Actions for supply chain security
18+
- [x] SSH host key verification (MITM protection)
19+
- [x] Concurrency controls for race condition prevention
20+
- [x] Job timeouts to prevent resource exhaustion
21+
- [x] SECURITY.md policy document
22+
- [x] CODEOWNERS for review requirements
23+
- [x] Dynamic repository owner (not hardcoded)
24+
25+

80+
- [ ] Compliance documentation (GDPR, etc.)
81+
- [ ] License compliance checking
82+
83+
### Disaster Recovery
84+
- [ ] Backup verification procedures
85+
- [ ] Mirror promotion playbook (if GitHub unavailable)
86+
- [ ] Recovery time objectives (RTO) documentation
87+
88+
---
89+
90+
## Phase 5: Framework Development
91+
92+
*Pending project direction - the following are suggested based on "MAA Framework" naming:*
93+
94+
### Core Framework
95+
- [ ] Define framework purpose and scope
96+
- [ ] Establish coding standards
97+
- [ ] Create project structure
98+
- [ ] Set up dependency management
99+
100+
### Developer Experience
101+
- [ ] Local development setup
102+
- [ ] Testing framework
103+
- [ ] Code formatting/linting
104+
- [ ] Pre-commit hooks
105+

## Reporting a Vulnerability
10+
11+
If you discover a security vulnerability in this project, please report it responsibly:
12+
13+
1. **Do NOT** create a public GitHub issue for security vulnerabilities
14+
2. Send a private report to the repository maintainers via GitHub's private vulnerability reporting feature
15+
3. Include as much detail as possible:
16+
- Description of the vulnerability
17+
- Steps to reproduce
18+
- Potential impact
19+
- Suggested fix (if any)
20+
21+
## Security Measures
22+
23+
This repository implements the following security practices:
24+
25+
### GitHub Actions Security
26+
27+
- **SHA-pinned actions**: All GitHub Actions are pinned to specific commit SHAs to prevent supply chain attacks
28+
- **Minimal permissions**: Workflows use the least privilege principle with `contents: read` permission
29+
- **SSH host key verification**: Known hosts are verified to prevent MITM attacks during mirroring
30+
- **Concurrency controls**: Prevents race conditions during parallel workflow runs
31+
- **Timeout limits**: All jobs have timeout limits to prevent resource exhaustion
32+
33+
### Secret Management
34+
35+
- SSH keys for mirror targets are stored as GitHub encrypted secrets
36+
- Mirror operations are conditionally enabled via repository variables
37+
- No secrets are logged or exposed in workflow outputs
38+
39+
### Force Push Warning
40+
41+
This repository uses `--force` push for mirroring operations. This is intentional for maintaining exact mirrors but means:
42+
- History on mirror targets will be overwritten
43+
- Tags on mirror targets will be force-updated
44+
- Only trusted maintainers should have push access to the main branch
45+
46+
## Dependency Updates
47+
48+
This project monitors for security updates in:
49+
- GitHub Actions (checkout, ssh-agent)
50+
- SSH host keys for mirror targets
51+
52+
## Contact
53+
54+
For security concerns, use GitHub's private security advisory feature or contact the repository maintainers directly.
